Answer:
D
Step-by-step explanation:
out of the choices
A) 2x-y=-2
3x+2y=-10
B) x+4y=3
2x+5y=3
C) 2x+3y=5
x-4y=-14
D) 3x+4y=15
x+y=5
only the system in D has a solution of x=5 and y=0
solve by substitution x+y=5 so x=5-y
plug into the other equation so 3(5-y)+4y=15
distribute 15-3y+4y=15 then minus 15 on both sides and combine like terms
so y=0 then put that value back into the other equation
so x+y=5 equals x+0=5 so x=5 this means the solution to the system of equations is the point (5,0)
Hope this helps! :)

<h2>
the associative property</h2>
Step-by-step explanation:
the associative property, the order of the numbers does not change their product

Answer: There are 667 owls for every 1000 squirrels.
Step-by-step explanation:
Since we have given that
Number of owls = 30
Number of squirrels = 45
If the number of owls and squirrels will continue to increase.
If there are 1000 squirrels, then the number of owls would be
Hence, there are 667 owls for every 1000 squirrels.
